+ (description
+ "SLY is Sylvester the Cat's Common Lisp IDE. SLY is a fork of SLIME, and
+contains the following improvements over it:
+
+@enumerate
+@item Completely redesigned REPL based on Emacs's own full-featured
+ @code{comint.el}
+@item Live code annotations via a new @code{sly-stickers} contrib
+@item Consistent interactive button interface. Everything can be copied to
+ the REPL.
+@item Multiple inspectors with independent history
+@item Regexp-capable @code{M-x sly-apropos}
+@item Contribs are first class SLY citizens and enabled by default
+@item Use ASDF to loads contribs on demand.
+@end enumerate
+
+SLY tracks SLIME's bugfixes and all its familar features (debugger, inspector,
+xref, etc...) are still available, but with better integration.")
